Application filed April l5,

`of "which the following is a specilicatoL My invention rela-tes to improvements in containers and 4has special' reference to uuproved `ineens for locking and releasing' concontainers such as small savings banlrs.

r*lhe object ot' my invention is to provide a simple means for locking the cover or top on a container such" as a coin box, which ineens shalloecupy but a. minimum oit dei'ith or space 5` which shall sirnulate a combination or" permutation lock; which shall be simple and cheap in construction; which shall prei scot no protuberances or projections to the coin or other contents; Whichshall be so con` i structed` tl'iat when the cover is locked to the bei; it can be turned indeiinitely in either` diy locking niechanisni. The loclrinpv` niechanisni c rection without unlockingl the cover; and which shall be readily unlocked by the application et a novel lrey.

One important feature o'i my invention re-v lates to a novel lrey ii'or application to the box and Which once applied is automatically proj ected into the operati ng; or loclrin mech nisni upon the rotation ot the cover in the right direction and automatically releases" itselt it turned in the Wrongl direction.

Another important 'feature ot my inven- `tion `relates to the provision a coin slot ggyuard which readily allows coins to enter into the boi; but which automatically closes against the ejection olf coins. i

My invention resides in a bant: preferably in the forni of aicircular boi; one end. ot

which constitutes a cover and which is rev and which are adapted tolenter thru notches in the top of the box and engao'e with the comprises a rotatable rneinbt-ir provided with notches tor permitting the ent-rance oit the lug-.s when registered with the notches in the top et the box, together with rneans tor lecitinp; `the cover to therotatable member vWith y its lugs out oi register with the notches in the rotatabl ineniberand Which is so ared i; ,it it prevents the escape ot the thru the notches in the top' of the box @ne ot the rings of the rotatable locking i member forms aguard cover to protect the lugs and the other ring and is provided with an internal Piange adapted toeontact with the cover member radially Within the lugs to prevent the pressure or thrust o' the coins binding the `rotatable rings Which are preferably made of thin sheet metal.

A tui-ther important `feature relates to the provision ot a spring member for locking the cover thru its lugs to the rotatable member, one end of this spring' is provided with a rounded projection adapted to yieldingly engragre the wall of the box and produce some light yielding trictional resistance to `the tree rotation ot 'the locking ring. The `rotatable gruard `ineinl'ier is adapted to be held in place againstthe top ot' the box by means ci' the coin guard at one point and apluralityY of legs or projections struck up out! oi the bottom ot the box at other points. This grua-id ring` is void ot any projection and presents a smooth continuous surface to the interior of the bon that' to the contents except only for a single relatively short slot thru .vhich the key is adapted to enter and also protects the contents troni contacting; with the coverlugs. i Y' rllhe coin slot guard is very simple in con-` struction, `the yielding` iueinbers being made of fiat spring); `nietal and are so supported that the yieldable means is free to permit the i coins to enter but is supported bythe casing of the box so that it cannot `yield in the op` posite direction to permit the coins tobe diS- cha l throirgrh the slot. i v invention will be more readily understood by reiterence to the accompanying drawings forming part of this specification and in which Figure 1 is a side elevation oi a container in the forni of a sinall savings bank embodyinpf my' invention; f

In said drawings, 1 reoresents the Container which in the termL shown is a. tiet Cylindrical boX comprising a cylindrical shell 2 closed at its lower end by means ot a bottom 3 and provided at its upper end with an inturned horizontal tlange 4- providing a centhe tral opening 5 thru which the contents of the container can be removed. The opening 5 is closed by ineens ot a cover G having an inner plate 6 provided on its under side with L-shaped lugs adapted to enter into the container beneath the tiange 4.- and be engaged with suitable locking devices i'or retaining' the cover upon the bex. 'lhe bottom 3 is formed outwardly as shown at S and the box is inished und the betteln is Covered by means of a plate 9 having un .annular flanged edge 10 and the plate 9 and its edge 10 is overlaid by a sheet 11 ot finishing material such es Celluloid the edge ot the piece of Celluloid being bent around the edge 10 and held between the edge l() and the lower edge oit the box. Likewise the cover 6 is recessed as shown at 12 und is likewise Covered and linished by means olli a plate 13 similar to the plate 9 which is likewise overlaid by atlixing e, sheet 111 oit Celluloid or other suitable :finishing material the edge of the sheet 11 being bent around the edge 15 ot' the cover sheet 13 and clamped between the edge 15 and the outer ot the cover 4f as best shown in Figure 141. The Celluloid Cover 14 is provided with suitable division marks 1G on its edge and the body ot the boi; is provided with an indicator' 17 so that es the cover is turned upon the bei: it will simulate and can be used in the same manner :is an index plate such as is ordinarily used with a combination or permutation lock. This feature is only 'for effect and not vlor its use. lletween the cover and the bottoni 3 the side wall of the box is provided with a Circumicerential coin slot 18 thru which coins can be introduced into the box or bank.

Special novel features ot my invention relate to the means tor interlocking the cover with the body oit the box and with the means for guarding the Coin slot to pie vent the removal of coins trom the bank thru the coin slot.

For the purpose ot interlocking the over l with the box l provide the flange 4; with a plurality of notches 19 in its inner edge spaced circumt'erentially the saine es the cover lugs 7 and. ot' a size to permit the easy pas age of the lugs i' thru the flange t and the libs 'T are long' enough so that when the Cover is placed upon the boi: und the lugs are passed thru the notches '19 the out 'turned prongs or feet 20 ot the cover lugs 7 extend and are located iu :i plane :1 short distance below the :thingie el so that theiv can rotate beneath the liange :is the cover is rotated. l. provide means beneath the fia-nge comprising :i rotatable locking ring` whien is adapted to Close the notches 19 utter the cover lugs have passed thru and prevent the withdrawal ot the cover lugs and the removal et the rover.

As best shown in Figure 9, these legs or supports rise into contact with the bottom surface of the ring 26 but do not bind the ring between the tops of the legs and the flange l leaving the rotatable 'member freely rotatable. ,ln place of one of the legs 59 l may maire use of my novel coin slot guard which l provide for permitting the introduction of the coins through the slot 18 andpreventing there* moval of the coin thru the slot.

rllhis novel coin slot guard designated generallyl by 60 comprises a sheet metal support `61 conformed to the cylindrical wall 2 of the casing and secured by foot lugs 62 to the bottom 8 of the casing and arranged just within `the slot 18. The end portions 68 of the support 61 are wide enough to contact with the bottom plate 8 and rise to the underside of the rotatablemember and thereby constitute a support therefor' if euch is desired. The middle portion of the support 61 is cut away forming a slot 6414 arranged opposite to and in registry with the slot 18 and thru which the coins can enter past the support 60 to the box. The upper and lower bars 65 and 66 forming the upper and lower edges of the slot 64 are bent or formedinwardly at their adjacent edges 67 as shown in liligure 14: so that these two bars are iuclined inwardly at an angle of substantially 800 to the outer wall of the box. The slot 64 is wider than the thickest coin which the box is adapted to receive and l provide a yieldable guard carried by the support 61 adapted to yield to permit the insertion of the coins andto automatically prevent the ejection or removal of the coins thru the coin slot. For this purpose l provide two spring members 67 secured to the support 61 and carried thereby. rlhese members. are each made of flat spring sheet metal as best illustrated in ligure 12 and each is prow vided with two longitudinal arms 68 at one end and with a slot 69 at the other end.

Each end of the support 61 is provided with a tongue 70 which is adapted to be received in the slot 69 of one of the spring members to secure them to the support as best shown in Figures l() and 11. The arms 68 are adapted to lie cio-incident with bars 65 and 66 and 'their free ends 71 are arranged adj athese bars are slightly narrower at their middle portions than at their ends to provide space between the lower bar and the bottom of the box and between the upper bar and the underside of the rotatable member to receive portions of the spring forming` hooks for retaining the springs in pon sition, For the purpose of providing the projections which guard the coin slot l provide a lateral prong 72 extending inwardly from the free end of each arm 68 which are adaptedto be turned inwardly or away from the shell of the boi; thus providing a tapered opening between them for the entrance of the coin. As the coin is entered thru the slot 18 against the prongs 72 the spring arms 68 are forced inwardly into inclined posi tions as shown by dotted line in Figure 14 spreading the prongs 72 apart and permitT ting the coin to enter freely into the coin box.` To prevent the coin distorting the springs and carrying them thru the opening in the support 61 l provide outwardly extending projections .78 on the free ends of the arms 68 adapted'to be formed into hooks for engaging the upper and lower edges of the bars 65 and 66 respectively. As best shown iu lltigure 14 it will be seen that if a coin is projected against `the inner ends of the projections 72 from within the box it vwill press directly against the said ends and press the spring arms 68 outwardly against the wall 4of the box and as they cannot yield any farther the opening between them cannot be made large enough to permit the escape of a coin. The hoolrs 78 are `freely movable around the outer edges of the bars 65 and 66and the springs arefree to respond to the pressure "of the coin to permit the coin to enter the box but cannot be distorted too `much as they 'are pressed against the bars 65 and 66.

Preferably for making the projections 72 at the inner ends of the arms `68 long enough to form suitable curved guards for the coin slot l maire the member 6T in the fiat form shown in ,Figure 12 the arms 68 being outwardly inclined relatively A to each other spreading their outer ends apart so that by severing the bar connecting their outer ends l. provide prongs of sufficient length. ln Figure 13 l have shown a modied manner of producing prongs of sufficient length without the necessity of outwardly inclining the arms in their process of manufacture. ln this form the two prongs 72 on the members 6i are offset from each other so as to enable me to malte each prong the full length from arm to arin thus avoiding the necessityY of forming the member 67' after the production of the arm to bring the arms 68 parallel with each other and reducing the width of metal necessary from which to produce the spring members.` It will be understood that after the member 67 has 'whether stationary n not be freed from.

been formed as shown in Figure l2 the arms are made parallel by oriniping up the portion 74 between the arms at their connected ends in a manner familiar to those skilled .in the art of manufacturing metal artic-les.

In Figure 22 I have shown a modified form of locking device. In this form I provide a, stationary U-shaped guard ring 75 having an outer flange 7 6 turned up at its edge and an inner flange 77. The outer liange 7G is adapted to contact with the body flange 4 adjacent to the outer wall 2 of the box and the inner flange 7 T to contact with the cover 5 just within the cover lugs 7 and thus forni a solid and rigid guard for the locking member providing a suitable liatringlike channel 7S in which the locking member freely rotates. In this form the inner locking ring 79 which takes the place of the guard ring in the first form is provided at its outer edge with an upturned flange 80 adapted to contact with a fiat tumbler or locking ring Sl at its outer edge the two rings 79 and 81 being spaced apartfor receiving the locking lugs 7 between them and these rings being formed similar to the rings already described for interloelment with the cover lug and provided with suitable notches for registering with the notches in the flange t for receiving and releasing the cover lugs. In this formv the stationary guard ring 75 is provided with a suitable opening 82 in proper relation to the coin slot 18 for receiving the key projection 47 for releasing the cover lug from the spring 35 in theimanner already described. Preferably I interlock the ring 79 with the ring 8l by means of interlocking lugs 83 and Sl similar to the interlocking lugs 3l and 82 already described in relation to the rings 26 and 2l.

The stationary guard ring 75 is forced into position and is formed to fit so tightly within the wall 2 of the boX that it requires no other fastenings and I can dispense with the legs 59.

It will now be seen that the guard ring or rotatable protects the locking ring against the pressure of the contents of the container and the contents of the'container are protected by the guard ring from the cover lugs.

It will now be understood that I have provided a very simple means of locking` thc cover upon a box leaving the cover rot-at able and simulating` a. permutation or combination lock in that the cover can rotate to any extent in either direction when interlocled with the rotatable member and canthe box until unlocked bv means of the key and furthermore that the construction is simple and provides a box in which no protuberances are movable in contact with the coins as such protuberances tend to bunch the coins or wear upon them and are particularl;Y objectionable when tho boX .is used for the storage olf jewelry or such like delicate eziilicnsive articles.
